Air China Limited (AIR CHINA), referred to as "Air China", was formally established in Beijing in 1988. Air China is a major airline transportation company controlled by China Aviation Group Corporation. It is jointly known as China's three major airlines with China Eastern Airlines Co., Ltd. and China Southern Airlines Co., Ltd.
China International Airlines Civil Aviation Business Building is located at No. 15 West Chang'an Street, Xicheng District, Beijing. The project uses our DBL-APF active filter for harmonic control. This major project uses our company's products to fully demonstrate the customer's recognition of Dibor's electrical quality.
The DBL-APF active power filter is connected to the grid in parallel, and the load current is monitored in real time by high-precision sampling CT, converted into a signal readable by the digital processor, and then subjected to a series of operations to control the core by PWM modulation. The intelligent power module outputs the current with the same harmonic component and opposite phase, which achieves the purpose of eliminating harmonics and purifying the power grid.
